Dragon Quest: The Adventure of Dai

Young Dai lives on Dermline Island, where he dreams of being a Hero. One day, a Hero and his companions come to the island. Dai is excited at first, but their true intent is to steal his best friend, Gomechan, the mythical Golden Metal Slime.

A dark power affects Dai's monster friends, driving them berserk. Brass tries to get Dai to leave and as they argue, a Hero trainer arrives to inform Dai that the Dark Lord has returned.

Avan turns into a dragon and attacks Dai, who fights back to no avail; as Dai clears his objective, someone enters the island.

Avan is overpowered by Hadlar, who is now stronger than ever. To protect his students and the world, Avan gathers the last of his strength and faces Hadlar. Dai can do nothing but watch. Finally, the showdown between Avan and Hadlar is concluded.
